Abstract
Abstract The prime objective of this invention is to direct and control the heat produced on the top of any portable heater measuring on the top 6 to 12 inches in diameter and using gasoline, kerosene and propane gas. Heat is directed up to 180 degrees by the use of a centrally perforated base flange and two side flanges that move in and away from the base flange. When the flanges are attached to the heater in the handle holes normally provided by the manufacturer a unique tunnel effect is created and moves up and down as required and the holes in the center of the base flange allow proper air circulation resulting in efficiency and effective heat pattern.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
158 words
A heater heat-deflector comprising incombination: a sheet element having heater unit-mounting means located at each of two of first opposite side-edges thereof, the heater unit-mounting means being adapted for mounting one of the first opposite side edges onto one side portion of a heater unit, and for mounting a remaining one of the first opposite side edges on an opposite side of the heater unit, such that the sheet element extends above and a predetermined distance above the heater unit sufficiently to deflect rising heat; said sheet element having ventilation through-space extending upwardly through the sheet element at at-least one point located substantially in alignment between said one and said remaining one of said first opposite side edges at a point adapted to be over the heater unit and at-least one telescopable deflector flange-sheet mounted on and extendable from and retractable to at-least one of said other second opposite edges, and being telescopable in to and fro directions.
Claim 2
Dependent Claim
158 words
A heater heat-deflector comprising incombination: a sheet element having heater unit-mounting means located at each of two of first opposite side-edges thereof, the heater unit-mounting means being adapted for mounting one of the first opposite side edges onto one side portion of a heater unit, and for mounting a remaining one of the first opposite side edges on an opposite side of the heater unit, such that the sheet element extends above and a predetermined distance above the heater unit sufficiently to deflect rising heat; said sheet element having ventilation through-space extending upwardly through the sheet element at at-least one point located substantially in alignment between said one and said remaining one of said first opposite side edges at a point adapted to be over the heater unit and at-least one telescopable deflector flange-sheet mounted on and extendable from and retractable to at-least one of said other second opposite edges, and being telescopable in to and fro directions.
Claim 3
Dependent Claim
25 words
A heater heat-deflector of claim 1, in which said ventilation through-space comprises a plurality of substantially lineally positioned consecutive openings substantially in series with one-another.
Claim 4
Dependent Claim
55 words
A heater heat-deflector of claim 2, in which said plurality are located spaced-away from other second opposite edges located at opposite ends of an imaginary axis extending substantially transversely to said lineally positioned consecutive openings, a distance such that the ventilation through-space is located substantially directly above a primary heat source of the heater unit.
Claim 5
Dependent Claim
22 words
A heater heat-deflector of claim 3, including separate ones of said telescopable flange-sheets mounted on each of said other second opposite edges.
Claim 6
Dependent Claim
30 words
A heater heat-deflector of claim 4, in which said sheet element along a direction extending between said one and said remaining one of said first opposite side edges, is arch-shaped.
Claim 7
Dependent Claim
44 words
A heater heat-deflector of claim 5, in which said heater unit-mounting means is detachably mountable on a heater unit and includes apertures through said sheet element adapted to receive a male member therethrough such that the sheet element is pivotable thereon to and fro.
Claim 8
Dependent Claim
49 words
A heater heat-deflector of claim 6, including a handle having one end thereof mounted within one of said apertures at said one of said first opposite side edges, and having the remaining opposite other end mounted within said apertures at said remaining one of said first opposite side edges.
Claim 9
Dependent Claim
39 words
A heater heat-deflector of claim 6, including said male member and having male-threads thereon, and including a female-threaded member threadably mountable onto said male member adapted to intermittently secure said sheet element in any of desired pivoted alternate positions.
Claim 10
Dependent Claim
44 words
A heater heat-deflector of claim 1, in which said heater unit-mounting means is detachably mountable onto a heater unit and includes apertures through said sheet element adapted to receive a male member therethrough such that the sheet element is pivotable thereon to and fro.
Claim 11
Dependent Claim
39 words
A heater heat-deflector of claim 9, including said male member and having male-threads thereon, and including a female-threaded member threadably mountable onto said male member adapted to intermittently secure said sheet element in any of desired pivoted alternate positions.
